About

Helion Energy is a fusion energy company working to develop the first commercially viable nuclear fusion power plant. Founded in 2013 and headquartered in Everett, Washington, Helion has pioneered a unique approach to fusion: instead of using deuterium-tritium (D-T) fuel like most fusion programs, Helion uses deuterium-helium-3 (D-He3) fuel with a proprietary field-reversed configuration (FRC) reactor design that simultaneously generates electricity directly through electromagnetic induction — potentially skipping the turbine step that adds complexity to other fusion approaches.

About

Commonwealth Fusion Systems (CFS) is a fusion energy company spun out of MIT's Plasma Science and Fusion Center in 2018, commercializing decades of fusion research through a proprietary approach using high-temperature superconducting (HTS) magnets. CFS's strategy centers on making fusion magnets much stronger than previously possible: HTS magnets can achieve field strengths of 20+ Tesla (more than twice conventional magnet capability), which allows fusion reactors to be dramatically smaller and cheaper — potentially shrinking a fusion power plant from stadium-scale to building-scale. The company's first demonstration reactor, SPARC, is under construction in Devens, Massachusetts.
